Overhead Conductor
For sagging:
• Pocketbook-style: Pocketbook grips must be clean in the conductor grooves. The nuts
used to close the grip must be free-running (easily turned full length by hand). Grips
must be tested per the manufacturer requirements prior to use. The bolts must be
snugged-up and then tightened with at least five passes applying full torque
recommended by the manufacturer.

• Klein “Chicago-style”: Klein grips must be of catalog number 1628-XX and exactly sized
to the conductor diameter to minimize strand distortion. Klein grips are the most
commonly used grip and have an excellent track record.
